Generalization of the Kaplan-Meier estimator for fuzzy lifetimes
Abstract
This proposal provides a generalization of the Kaplan-Meier estimator, where lifetimes are considered fuzzy numbers. This proposal is consistent with a much more realistic context to the measurement process considering the imprecision of human nature. To achieve our goal, concepts such as relative frequency and fuzzy classes are given. Moreover, some asymptotic results are presented, together with an application and comparison with the conventional estimation method.
